10x - 5y = -25
l0x+8y=14

Greetings,

I hope you and your family are staying safe and healthy!

x = -1 and y = 3

Step-by-step explanation:

Let's start by solving for

Add 5y to both sides

Now we need to divide both sides by 10

That's not the answer for x. We are not done yet :)

Now we need to substitute for

Now we need to simply both sides

Now we need to add 25 to both sides

We have the valuee for y! Now we need to find the value for x

To find the value of x, we need to substitute 3 for y in:

Therefore,

The answer is x = -1 and y = 3
